We often receive bugreports from windows or OSX users with keyboard problems. For example on windows changing the keys ” to ¨ and ‘ to ´. Or on OSX the square brackets  are not possible on a German keyboard layout (see https://bugzilla.gnome.org/show_bug.cgi?id=737547), or curly braces not on AZERTY layout (see https://bugzilla.gnome.org/show_bug.cgi?id=692721).
From what I understood this is caused by gtk handling the keyboard events itself, instead of waiting for the key-value that the operating system provides.
Is there a way how this can be fixed? Either in Bluefish or in GTK?
